Browning® 1045699 BRO1VP681 1/4

The principle of a variable pitch sheave is that the threaded angular faced discs forming the V-shaped groove in which the belt rides are movable. VP sheaves consist of a male with a threaded barrel, and a female with a threaded bore. The male section with threaded barrel has flat surfaces at 180 deg increments that allow a flat surface for the setscrew to mate with. When the discs are moved toward each other, the belt rides higher in the groove and the pitch diameter of the sheave is larger which increases the driven speed. When the discs are moved away from each other, the belt rides lower and the pitch diameter is smaller decreasing the driven speed. The common term for this speed adjustment is called number of turns open from closed position.

• Twice balanced after assembly
• Tightened micro-finish on groove walls for increased belt life
• Variable speed sheaves through 5 grooves, precision balanced to provide smooth vibration-free performance
• Largest selection in the Industry - Browning offers the widest range of variable speed sheaves in the market today
• VP sheaves consist of a male with a threaded barrel, and a female with a threaded bore
• The male section with threaded barrel has flat surfaces at 180 deg increments that allow a flat surface for the setscrew to mate with
• When discs are moved toward each other, the belt rides higher in the groove and the pitch diameter of the sheave is larger which increases the driven speed
• Combination Groove - All Browning B5V Sheaves permit the running of A, 4L, B, 5L and 5V Belts to be run in them, thus providing a variety of different pitch diameters and horsepowers
• Broad horsepower coverage - The B5V is available in 1 through 6 grooves allowing it to cover from 5 to 125 horsepower drives
• Incorporates Browning Split Taper Bushing - The only bushing system that provides a true Key-to-Key drive to both the shaft and the hub
• New Casting design - The B5V castings were developed using CAD and Finite Elements Analysis to determine where to add and eliminate material
